Abstract
1290907 Mining machines JOY MFG CO 5 Dec 1969 [24 Dec 1968 (2)] 59596/69 Heading E1F A mining machine 10 comprises a pivoted boom 18 carrying a cutter chain 76 at each side of which is a drum cutting head 78 including an extension 80 extensible laterally of the boom, and a gathering head 26 feeding a rearwardly extending conveyor 30. The boom and the head are pivoted vertically by rams, Fig. 3 (not shown), and the chain and drum cutting heads are driven by motors 36. The cutter chain 76 is substantially equal to the width of the conveyor 30 and is preferably driven at a speed exceeding that of the conveyor so that with the boom lowered it can cooperate with the conveyor to facilitate removal of mined mineral. The extensions 80 are extended and retracted hydraulically, Figs. 6 and 8 (not shown).
